I have a page that is using server push jpegs for streaming video. When I specifiy a xhtml doctype for this page, the video no longer displays. Without the doctype, the video displays correctly.
Reproducible: Always
Steps to Reproduce:
1. Go to a site with server push jpeg video (see URL attached) that has specified a (x)html doctype.
Actual Results:
The video image does not display. Only the contents of the alt attribute are shown.
Expected Results:
The server push jpeg will be displayed as a video.
I have also tried this with Firefox 1.0.7 on both Windows and Linux with the same behaviour. I also have a test page that has the doctype stripped to show that the jpeg push does work in that case. http://code.nees.buffalo.edu/flexTPS/test2.html

so I tried this with a trunk build today and wasn't able to reproduce it. With the doc type you see the loading icon for a sec before it starts going, but it seems to work OK. Not sure what the cause is on 1.0.x.
There was a server-push jpeg patch that went in at some point recently not sure if it was pre or post 1.8b5.
Can you test it on the trunk? I'll grab a newer branch build and see if it is busted there.
